48K143 - Walter 48-K-143 Spacer Washer, 1/4-Inch Thick for 5/8-11 Spindles

Precision Spacer for Angle Grinder Accessories

The Walter Surface Technologies 48-K-143 Spacer Washer is a critical accessory designed for industrial metalworking environments. Manufactured to precise tolerances, this washer features a thickness of 1/4 inch (approximately 6mm) and is engineered to fit standard 5/8-11 threaded spindles found on most North American angle grinders. In many abrasive applications, standard clamping nuts may not provide adequate pressure on thinner wheels, or an accessory may sit too close to the tool housing or guard. This spacer bridges that gap, ensuring a secure and safe fitment.

Constructed from high-quality steel, the 48-K-143 withstands the heat and vibration associated with heavy-duty grinding and finishing operations. It is particularly useful when mounting wire brushes, thin cut-off wheels, or specialty abrasive discs that require a specific offset from the grinder's backing plate. By ensuring the accessory is properly seated and clamped, this spacer helps prevent slippage, reduces vibration, and enhances operator safety. It is a genuine OEM part from Walter, guaranteeing compatibility and performance with their extensive line of power tools and abrasives.

Whether replacing a lost component or outfitting a tool for a specific task, this spacer washer is an indispensable item for the tool crib. Its robust design ensures it will not deform under torque, maintaining the integrity of the grinder's spindle assembly over long-term use.
